Reliable and compact

Used this in a small drone controller project. The size is perfect for tight spaces, and the power consumption is low. Flashing firmware via SWD is fast and reliable. No issues after weeks of continuous operation.

Great for industrial prototyping

We used several of these for initial proof-of-concept testing before moving to custom PCBs. The consistency between units is impressive. The temperature range seems adequate for indoor industrial environments.

Perfect for learning ARM architecture

This board is exactly what I needed to start my journey with STM32 microcontrollers. The pinout is clearly labeled, and it works flawlessly with the Arduino IDE using the STLink programmer. Great value for the price.

Good board but steep learning curve

The hardware itself seems fine, but if you are coming from standard Arduino boards, the setup process is a bit confusing. Make sure you have a proper ST-Link debugger before buying. Once set up, it works well.

Solid hardware, minor documentation gaps

The build quality is excellent and the chip runs stable at 72MHz. However, the included PDF manual was a bit sparse. I had to refer to the official ST datasheet for some specific register details. Still, highly recommended for prototyping.

5 FAQ

Q: Does this board come with an onboard programmer?

A: No, this core board does not have an onboard programmer. You will need an external ST-Link V2 or J-Link debugger to flash code onto the microcontroller.

Q: What is the maximum input voltage for the VIN pin?

A: The onboard regulator supports an input voltage range typically between 3.6V and 12V on the VIN pin, though we recommend staying below 9V for optimal thermal performance. The logic level is 3.3V.

Q: Does it support MicroPython?

A: Yes, the STM32F103C8T6 has sufficient flash and RAM to run MicroPython. You will need to flash the appropriate .bin firmware file for the specific board configuration using an ST-Link programmer.

Q: Is this compatible with the Arduino IDE?

A: Yes, it is compatible. You can use the Arduino IDE by installing the STM32duino board package. Select the 'Generic STM32F103C series' and choose the correct upload method (STLink).

Q: Can I use this for 5V sensors?

A: The microcontroller operates at 3.3V logic levels. While the board has a 5V pin for powering external modules, the GPIO pins are not 5V tolerant. You must use a logic level converter when interfacing with 5V sensors to avoid damage.
